you add 8 and 8 and the you add 9 6 and then you add 5 and 3.

You can change 399 to 400 and + 598 you get your answer it is easy you also said to add 8 plus 8 but it is really 8 plus 9

345 -298	568 -399	386 -297		546 -399		748 -198	427 -395	865 -799	768 -497
347-300=47 345-300=45-2=43	569-400=169

Change the problem to make it easier to multiply. For example, you can multiply one number by two
if you multiply the other by 1/2. Try making your own and solving it in the top row.

16 x 5

28 x 5

24 x 5

148 x 5

248 x 50

128 x 50

468 x 500

8x10=80 that is the same as 16x5

28x5=110 8x5=40 2x5=10+1=11

Multiply by Splitting

When one number of a multiplication pair has two digits, try splitting that number into two parts by dividing it by 2.
Example: 9 x 12
Split 12 into two parts: 12=6x2
Instead of 9x12 (9x6x2) think 9 x 6 and then double it.
9x6=54 Double 54 and you get 108.

1. 8 x 16

2. 5 x 22

3. 6 x 18

4. 7 x 14

5. 9 x 16
6. 12 x 24
